12 Claims. m1. 126-93) My invention relates to an improvement in hot water heaters and has, for one purpose the pro: vision of an oil burning hot water heater-which shall be economical to manufacture and efllcient I "in use.

Another purpose is the provision of improved means for removably securing the burner in position; I Other purposes will appear from time to time in the course of the specification and claims.

.The present application is a division of my co-pending application Serial Number 323,058, filed in the United States Patent Oflice on March 9, 1940.

-I illustrate my invention more or less diagrammatically in'the accompanying drawing wherein:-

Fig. 1 is a side elevation; Fig. 2is a section on the line 2+2 of Fig. 1

Fig. 3 is a section on an enlarged scale on the line 38 of Fig. 2; and

Fig. 4 is a detail.

Like parts are indicated by like symbols throughout the specification and drawing.

mary air inlets l8 and a top row of secondary air inlets 19. The arrangement of the air inlets is not of the essence of the present invention, as it may be applied .to'a widevariety of different types of burners. What is essential is that the burnershould have an open top aligned with I the vertical passage or space ;andsha1l have some "interfltting means, flange or the like, as,

indicated as at 20, whereby it may abut snugly 0 against the bottom of the partition 5, or some abutment portion thereof;

In order both to center the pot ill and to secure y it in position, I provide a lever structure, indicated as composed of two arms 2! and 22, which 15 may be ofspring stock, rod stock, or. the like.

Referring to the drawing, I illustrata ior ex- I ample, a drum type hot water heater, in which I may employ, for example, a cylindrical outer,

shell l, having a bottom member 2, a top memher 3, a central passage l, and a lower partition 5. A water inlet may be indicated at t, and an outlet at 'l. The details of the heating space or the coils, and the subjection oi the water to the heat or the burner are not indicated, as they do not of themselves form part of the present inventicn. What is essential is that whatever heat exchange mechanism may be employed, there shall be a preferably axial opening from top to bottom of the interior of the drum i, which is diagrammatically indicated as the passage :3.

.Access may be had to the space inthe drum below the partition 5, for example, through any suitable door aperture VI 0, closed by the removable doorv l l, which may be hinged as at I2, and pro.-

These arms are pivoted for example to brackets 23, located in the inner'iace of the wall Lgenerally opposite'to the door ii. The arms 2! and 22 are shown as secured to eachother at their 0 free ends, to provide what is in efiect a V-shaped spring lever. Pivoted to the end of the V is a compression member or link, which may include two screw-threaded members 20,, 25, the member '25 being provided with an eye 28, through which 5 the lever structure passes. This is ShOWn merely asone practical form of the structure, as it may be widely varied. The link may be adjusted for length by rotation of the nut ii, to which the members 24, and 25 arescrew threaded. Any

30 suitable fork or head ZS may be provided for the 30 may itself be employed as such an abutment.

vided with any suitable latch 53. The door may be made entirely removable if desired. I 7

it generally indicates a pot type-burner liav-v ing a slightly concave bottom l5, adapted to re- .ceive a liquid hydrocarbon delivered along the passage it, which may extendthrough the drum wail i and may be provided with any suitable removable securing means ILwhereby the burner,

it may be readily secured to or removed from the end of the' iueI passage I5, which=mayfor I example be of flexible copper tubing.

Theburner it is shown as having a generally I I burner may be very quickly assembled, and very cylindrical wall provided with a plurality of pri- In order to center the pot for quick insertion, I provide abutments 3U, 35, which are shown as adjustable along the arms 25, 22. They may be properly adjusted for any size of heater or pot, and held in position by set screws 31a. When so adjusted, andwhen the door is open and the lever structure is in the dotted line position of Fig. 2, the pot is simply pushed in through the door and slid along the lever structure until it strikes the.

abutmentsZ-Zli, 3 l It may be turned to the proper positionto be, secured to the preferably flexible oil inlet passage I 6. The-operator'then raises'the lever, and with it the pot, until the pot is properly ,seated against the partition 5,,or any appropriate 0 abutment member or members associated therewith. The fork 28 is then engaged with the abutment 29, or with the lower frame of the door shown at. 29c, and theresult is a firm thrust of the pot It upwardly into tight position. The

quickly removed for cleaning, replacement, re-

pair, or the like. The door ll may be closed,

or if desired it may be entirely removed.

Aligned with the central passage 4 is a flue structure which includes a vertical portion 40,

upwardly extending in vertical alignment with the burner l4 and the passage 4. 4| indicates a stack member or elbow, and 42 a horizontal member beyond the elbow,.which in turn communicates with any suitable flue or stove pipe 43. The angle member. is provided with any suitable aperture 44, which may be closed by a damper vane 45, pivoted as at 46. The'vane may be adapted for inspection of the flre and for lighting of the flre. when the damper is in closed position, the height bf the unit I is such that the operator can look directly downwardly through the hole 41 and see what the flame conditions are. I suggest a hole 41, but it will be understood, of course, that any suitable transparent material may be inserted in the vane or may form part or all of the vane or tive device, nevertheless many changes may be of parts without departing from the spirit of my invention. I therefore wish my description and drawing to be taken as in a broad sense illustrative or diagrammatic, rather than as limiting me to my precise showing.
